INK-SAVING ADJUSTMENT.

Specification of Letters Patent.

Patented April 9, 1907.

Application filed October 6,1905. Serial No. 281.617.

To all; w/mnt 212 may cancer/1,:

, 5,: Be it known that I, FRANK (J. JOHNSON, a citizen of the United States, residing at Portland, in the county of Cumberland and State V l of Mame, have invented new and usetul Im- 1 provements in Ink-Saving Adjustments, of which the following is a specilication.

This invention relates to improvements in adjustable attachments for inkstands, and is designed to provide an ink-cup l'or inkstands which will permit a certain predetermined quantity of ink to be admitted therein.

In inkstands as are usually constructed a stand is filled the person using the pen and i air into the ink-reservoir when the cup is screwed down. When it is desired to use my improved cup in inkstands of ordinary construction, I provide a llange J, interiorly threaded, as seen at II, said llange being surrounded by some compressible material, as cork, as seen at L.

This is inserted in the inkstand and the cup is screwed therein.

The llange is approximately the diameter of 1 the opening in the inkstand, and as 1t 1s sur- 1 rounded with some compressible material it can be easily forced into the opening in the j inkstand, making thereby a tight lit. The diihcultyls experienced, in that when the inki dipping the same into the ink is likely to dip the pen too far into the reservoir, this causing the ink to get upon the holder and in consequence soil the fingers of the user.

My improved device consists of a cup provided with a plurality of openings in the bottom adapted to set into an ordinary inkstand, the cup being capable of adjustment in a vertical direction and so arranged that but a limited quantity 01'' ink will be in the chainber at any one time.

In the drawings, herewith accompanying and forming part of this application, Figure 1 is a vertical sectional view of an inkstand embodying my improvement. Fig. '2 is a Vertical sectional view of an inkstand not originally made with my improved attachment, but showing the same in position and the means for holding the same thereon. Fig. 3 is an elevation of the ink-cup.

Same letters of reference refer to similar parts in all the figures.

In said drawings, A represents an inkstand of any construction, B representing the ink therein. The opening 0 at the top of the inkstand is interiorly threaded, as seen at D. Adapted to be screwed into said inkstand is a preferably cylindrical-shaped cup E, having a flange F, said cup being threaded on its exterior, as seen at G. Said cup is also provided with a plurality of openings H in the bottom thereof. The exterior of the cup is also provided with vertical slots I, the purpose of these being to allow the admission of cylindrical cup can then be adjusted to any required depth by screwing the same up or down.

The operation of my device is as follows: The ink is iirst placed in the ink-reservoir. The cylindrical cup is theninserted in the opening and screwed down to such a depth in the inkstand as would force the ink through the opening in the bottom of the cylinder to such height in the cylinder as desired by the user. The ink is usually kept at such. a height in the cylinder as will cover the pen when the pen is inserted therein. In order to prevent unnecessary evaporation when the inkstand is not in use, the cup may be screwed outnardly, thereby allowing the ink therein to how back into the reservoir. The cup then serves as a stopper for the opening.

Ilaving thus described my invention and its use, I claim The combination with an ink-well having a threaded bushing therein of an ink-well stopper comprising an externally-threaded cylindrical cap having a projecting flange at the top, openings in the bottom and an airduct in its vertical wall, whereby when the cap is screwed home the air-duet is closed by said projecting flange.

In testimony whereof I have signed my name to this specification, in presence of two subscribing witnesses, this 28th day 01 September, 1905.
